To all whom it may concern Be it known that l, CLARENCE P. Nears, a citizen of the United. States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented a new and Improved Carbureter, of which the following is a full, clear, and exact description.

This invention relates to carbureters and has for an object the provision of an improved arrangement which will supply fuelin proportion to the speed of the engine towhich it is connected.

Another object in view is to provide an improved arrangmient whereby the fuel is taken up-in small quantities and then mixed with the air while more or less finely divided before passing intp the cylinder of the enune. v c A still further object of the invention is to provide a carburetor in which is mainmember operated by the suction of the en- .gine for dividing the oil into fine particles and then mixing the same with air to the discharge of the oil.

A further object is to provide a carbureter with a rotating wheel structure having previous a perforated disk arranged on the periphery and blades arranged in a transverse plane together with means for maintaining the supply'of oil through which said disk passes in order that the disk may supply small and more or less finely divided quantities of oil,

the suction of the engine acting on said blades for rotating the wheel structure in proportion to the speed of the engine.-

r 6 extending into exhaust manifold and forming a heating-coil? therein. The carburetef 4 is provided with the usual butterfly I valve 8 operated by the. crank or arm 9 to which a controlling rod or cable 10 is connected whereby the carburetor may be throttied down at any time.

The carbureter 4: is provided with a casim 11 preferably formed in two parts and connected in any suitable manner, said cas ing having an'inlet opening 12, which receives a supply of fuel, as for instance gasolene, kerosene or other similar fuel from a container 18 carrying a fioat'l i, said float operating a suitable valve in the extension 15 of container l3'whereby the fuel entering. through pipe '16 may be maintained at substantially the level shown in Fig. 3.

The casing 11 is formi with an annular chamber 17 which is circular in cross section and which merges into an annular chamber 17 preferably rectangular in cross section, as shown in Fig. 3. The chambers just le scribed accommodate a wheel 18 supported by a shaft 19 in suitable hearings in the casing 11, said bearings having caps 20 and 21 for properly holding the shaft 19. The cap 21 is provided with an opening 22 said cap holding in place a glassor transparent disk 23' which prevents dust and dirtfrom entering into the hearing, but which allows any one to observe the shaft 19 at any time in order that the operator may see whether or not the .wheel 18 is turning. It is of course evident that the wheel 18 is rigidly- 'connectedby a key or otherwise to the shaft The wheel centrally of the wheel 18 and forming the being provided with a plurality of apertures 27. The ring 26 extends into the chamber 17, but does not fill said chamber.

In order to prevent a circulation of oil inv said chamber a plurality of'fins or blades 28 and 29 are provided which extend from periphery thereof is a flz" ring 26, said ring the Walls of the casing and come almost in contact with ring 26. These fins will allow the oil carried in the aperture 27 to freely pass, but resist the passing of any additional oil or any air.

In operation when the engine to which the carbureter is connected is turned over the suction produced thereby will cause air to enter through pipe 5 into the lower part of the casing and pass from said lower part to the discharge throat or mixing chamber '30 and will cause the wheel 18 to rotate and as it rotates the lower part of the ring 29 will pass through the 011 fed in the lower part of chamber 17 through the passageway 12. .The oil in the various apertures 27 will pass the inlet opening of the pipe 6 and as the suction of the engine is drawing in air through this pipe, which air passes through 20 the apertures 27, the same willlmix with the oil in said apertures and carry the oil into the chamber 30 and will there "mix With the air from pipe 5 so that aproper combustion mixture may be discharged into the manifold tube. Asthe air from pipe 6 is heated in coil .7 it will be observed that the first airstriking the fuel will be warm or hot, as the case. may be, "and will thereby produce a better-carburation of the finely-di- 80 vided parts of oil carried by ring 26 in aperteres 27. This heated air and oil mixture is diluted by the cold air in chamber 30 and then fed into the manifold. As the ring 26 .usually rotates at an appreciable speed. only *a small quantity willusually be carried up by the ring in the apertures 27 whereby the heated oil may quickly and readily mix therewith so as to produce almost perfect rkiarburation in the case of gasolene and a 20; ireryefiective carburation in the case of kerosene or other comparatively heavy .oils. *Ais'theengme moves faster and faster the suction will become greater and greaterand' consequently the Wheel 18 will rotate faster t tle pipe 5 so as to regulate the auxiliary air to any desired extent in order tq secure a proper mixture.

What I claim is v 1. In a carbureter of the character described, a casing provided with a central chamber and an auxiliary chamber radiating therefrom, means for maintaining a predetermined quantity of oil in the lower part of said, auxiliary chamber, a wheel arranged in said casing formed with blades fitting in said'central chamber and with a disk fitting in said-auxiliary chamber, said disk being formed with a plurality of openings whereby when said wheel is rotated small quantities of oil will be taken up in said openings,

scribed, a casing, means for maintaining a level of oil in the bottom part of said casing,

said casing being provided with an annular outer chamber and an annular inner cham:

ber merging into the outer chamber, a wheel arranged in said casing provided with a plurality of spokes, a blade connected with each of said spokes, said blades being arranged in said inner chamber and extending transversely thereof so as to loosely fit .the inner chamber, a ring connected to the outer end of said spokes and extending into the said outer chamber, said ring being provided with a plurality I of comparatively small apertures, said ring being adapted-to, pass through said level of oil whereby small quantities of oil are taken up in said apertures, means for dlrectmg air lnto sald 1nner chamber for engaging said bladesfor rotating said wheel when suction is produced in the discharge throat of the carbureter, and means for directing air against the upper part of said wheel for causing a carburation of the oil, said last-mentioned air passing to said throat and mixing with the air from said inner chamber.
